It must be rather weird at first for a new animal in a household.
Any new Siamese kittens we've had (always two at a time) have initially found a 'safe spot' to retreat into while, like Dreamy, they'd keep watching and assessing everything that went on around them.

I remember Minty and Murphy as tiny kittens crawling backwards under a table in the study, their little eyes like saucers. They stayed there for ages getting a 'feel' for the house.

Dreamy sounds intelligent and alert Bonzo.
